Extended Cyclotron Resonant Heating of the Turbulent Solar Wind
Trevor A. Bowen, Ivan Y. Vasko, Stuart D. Bale +8
Circularly polarized, nearly parallel propagating waves are prevalent in the solar wind at ion-kinetic scales. At these scales, the spectrum of turbulent fluctuations in the solar…
Proton and Alpha Driven Instabilities in an Ion Cyclotron Wave Event
Michael D. McManus, Kristopher G. Klein, Davin Larson +8
Ion scale wave events or "wave storms" in the solar wind are characterised by enhancements in magnetic field fluctuations as well as coherent magnetic field polarisation signatures…
Interchange reconnection as the source of the fast solar wind within coronal holes
S. D. Bale, J. F. Drake, M. D. McManus +13
The fast solar wind that fills the heliosphere originates from deep within regions of open magnetic field on the Sun called coronal holes. The energy source responsible for acceler…
Alpha-proton Differential Flow of the Young Solar Wind: Parker Solar Probe Observations
P. Mostafavi, R. C. Allen, M. D. McManus +5
The velocity of alpha particles relative to protons can vary depending on the solar wind type and distance from the Sun (Marsch 2012). Measurements from the previous spacecraft pro…
Nonlinear Interactions in Spherically Polarized Alfvénic Turbulence
Trevor A. Bowen, Samuel T. Badman, Stuart D. Bale +8
Turbulent magnetic field fluctuations observed in the solar wind often maintain a constant magnitude condition accompanied by spherically polarized velocity fluctuations; these sig…
Strong perpendicular velocity-space in proton beams observed by Parker Solar Probe
J. L. Verniero, B. D. G. Chandran, D. E. Larson +16
The SWEAP instrument suite on Parker Solar Probe (PSP) has detected numerous proton beams associated with coherent, circularly polarized, ion-scale waves observed by PSP's FIELDS i…
A solar source of Alfvénic magnetic field switchbacks: {\em in situ} remnants of magnetic funnels on supergranulation scales
S. D. Bale, T. S. Horbury, M. Velli +17
One of the striking observations from the Parker Solar Probe (PSP) spacecraft is the prevalence in the inner heliosphere of large amplitude, Alfvénic magnetic field reversals terme…
Plasma Properties, Switchback Patches and Low -Particle Abundance in Slow Alfvénic Coronal Hole Wind at 0.13 au
Thomas Woolley, Lorenzo Matteini, Michael D. McManus +8
The Parker Solar Probe (PSP) mission presents a unique opportunity to study the near-Sun solar wind closer than any previous spacecraft. During its fourth and fifth solar encounter…
Inferred Linear Stability of Parker Solar Probe Observations using One- and Two-Component Proton Distributions
K. G. Klein, J. L. Verniero, B. Alterman +12
The hot and diffuse nature of the Sun's extended atmosphere allows it to persist in non-equilibrium states for long enough that wave-particle instabilities can arise and modify the…
The Contribution of Alpha Particles to the Solar Wind Angular Momentum Flux in the Inner Heliosphere
Adam J. Finley, Michael D. McManus, Sean P. Matt +14
An accurate assessment of the Sun's angular momentum (AM) loss rate is an independent constraint for models that describe the rotation evolution of Sun-like stars. In-situ measurem…
Enhanced proton parallel temperature inside patches of switchbacks in the inner heliosphere
L. D. Woodham, T. S. Horbury, L. Matteini +16
Switchbacks are discrete angular deflections in the solar wind magnetic field that have been observed throughout the heliosphere. Recent observations by Parker Solar Probe (PSP) ha…
The Electromagnetic Signature of Outward Propagating Ion-Scale Waves
Trevor A. Bowen, Stuart D. Bale, J. W. Bonnell +7
First results from the Parker Solar Probe (PSP) mission have revealed ubiquitous coherent ion-scale waves in the inner heliosphere, which are signatures of kinetic wave-particle in…
Parker Solar Probe observations of proton beams simultaneous with ion-scale waves
J. L. Verniero, D. E. Larson, R. Livi +19
Parker Solar Probe (PSP), NASA's latest and closest mission to the Sun, is on a journey to investigate fundamental enigmas of the inner heliosphere. This paper reports initial obse…
Cross Helicity Reversals In Magnetic Switchbacks
Michael D. McManus, Trevor A. Bowen, Alfred Mallet +17
We consider 2D joint distributions of normalised residual energy and cross helicity during one day of Parker Solar Probe's (PSP's) first encounter as a functi…
